...Gravity supports procedural programming, object-oriented programming, functional programming, and data-driven programming. Thanks to special built-in methods, it can also be used as a prototype-based programming language. Gravity has been developed from scratch for the Creo project in order to offer an easy way to write portable code for the iOS and Android platforms. It is written in portable C code that can be compiled on any platform using a C99 compiler. The VM code is about 4K lines long, the multipass compiler code is about 7K lines and the shared code is about 3K lines long. The compiler and virtual machine combined add less than 200KB to the executable on a 64-bit system.

This project reimplements from scratch the RPL language made popular by HP programmable calculators, in portable C/C++. The main goal is to release a complete computing environment for various targets. There's currently 4 active targets: the HP 50g, HP39gs and HP40gs calculators and a PC simulator (see the downloads section!). Other ports are planned for the future.
